Fill Layers

A Fill Layer is a special layer that Krita generates on-the-fly that can contain either a pattern or a solid color.


By default, the dialog selects the flat color fill. This fills the layer with a singular color. Since version 4.2, newly created colored fill layers will be assigned to the currently active foreground color.

However, there are many more options, with more complex features:

Painting on a fill layer

A fill-layer is a single-channel layer, meaning it only has transparency. Therefore, you can erase and paint on fill-layers to make them semi-opaque, or for when you want to have a particular color only. Being single channel, fill-layers are also a little bit less memory-consuming than regular 4-channel paint layers.
